Problems solved by technology

Although this method has high face pinching efficiency, the realization effect in the 3D face pinching scene is poor. Specifically, when predicting the face pinching parameters in this way, the end-to-end prediction is directly based on the 2D face image. The pinched face parameters predicted in this way lack three-dimensional spatial information. Correspondingly, the virtual facial images generated based on the pinched face parameters usually have serious depth distortion problems, that is, the three-dimensional structure of the generated virtual facial images is different from that of real faces. The three-dimensional structure of the virtual facial image is seriously inconsistent, and the depth information of the facial features on the virtual facial image is very inaccurate

Abstract

The embodiment of the invention discloses an image processing method and a related device in the field of artificial intelligence, and the method comprises the steps: obtaining a target image which comprises the face of a target object; determining a three-dimensional face reconstruction parameter corresponding to the target object according to the target image; based on the three-dimensional face reconstruction parameters corresponding to the target object, constructing a three-dimensional face grid corresponding to the target object; converting the three-dimensional face grid corresponding to the target object into a target UV image, wherein the target UV image is used for bearing position data of each vertex on the three-dimensional face grid corresponding to the target object; determining a target face pinching parameter according to the target UV graph; and generating a target virtual face image corresponding to the target object based on the target face pinching parameter. According to the method, the three-dimensional structure of the virtual face image generated by face pinching can be consistent with the three-dimensional structure of a real face, and the accuracy of the virtual face image generated by face pinching is improved.

Description

technical field [0001] The present application relates to the technical field of artificial intelligence, in particular to an image processing method and related devices. Background technique [0002] Face pinching is a function that supports users to customize and modify the face of virtual objects. At present, game applications, short video applications, image processing applications, etc. can provide users with the function of pinching faces. [0003] There are mainly two ways to realize the face pinching function. One is to pinch the face manually by the user, that is, the user manually adjusts the face pinching parameters to adjust the facial image of the virtual object until the virtual facial image that meets their actual needs is obtained. until. Under normal circumstances, the face pinching function involves a large number of controllable points. Correspondingly, there are many face pinching parameters that can be adjusted by the user. Users often need to spend a l...
